This is the most recent version (2013 FZEX) of Western Digital's best performing consumer storage drive, its predecessor was the WD1002FAEX which is now four years old. With average sequential read/write speeds of 150 MB/s this version outperforms its predecessor by a whopping 50%. Small file random 4K speeds have remained broadly unchanged with average read/write rates of 0.9/2.19 MB/s. Overall the 2013 WD Black has a very good performance profile and it also represents reasonable value for money, at least in the 1TB category. There are some good alternatives to the 2013 Black including the 2012 Blue. Looking at the 2013 Black vs 2012 Blue shows that both drives have similar performance. Power consumption (6.8/6.1 Watts active/idle) and noise levels (29.5 dBA) are also identical making it a tough call between the two. There is however, as always, better value amongst the larger capacities. [Feb '14 HDrivePro]


The 2TB Toshiba DT01ACA200 is a 3.5" desktop hard drive. This model sports a rotation speed of 7,200 RPM and is reasonably power efficient for a 2TB desktop drive consuming just 6.4 Watts when loaded and 5.2 Watts when idle. The DT01ACA200 has impressive performance with peak sequential read/write speeds of 193/182 MB/s and peak 4k read/write speeds of 1.16/2.28 MBps. These raw figures produce an effective speed of 141 MBps which ranks the 2TB DT01ACA200 amongst the top handful of 2TB hard drives. Not only is the 2TB DT01ACA200 a great performer but it is also priced aggressively and therefore represents superb value for money for a 2TB capacity drive. Comparing the 2TB and 3TB versions shows that performance is very similar but the 3TB offers 50% more capacity for just 25% more cash which makes the difference between good and great value for money. [Nov '14 HDrivePro]
